WestESIM provides reliable signal in key hubs of the Danube Delta, such as Sulina and Tulcea. However, as you venture deeper into the remote channels and untouched wilderness of this biosphere reserve, expect connectivity to transition to 3G or become intermittent. For critical communication, plan accordingly, but enjoy sharing your experiences from the main areas.
